Abstract
A process for preparing a metal oxide catalyst for acrylic acid production which comprises calcining a metal compound mixture at 400° C. or higher to prepare a metal oxide powder comprising Mo, V, Sb, and at least one element selected from the group consisting of Nb and Ta, and supporting a compound comprising at least one element selected from the group consisting of Sb, Tl, Se, As, Pb, Sn, Ag, Cu, Ru, and Rh on the metal oxide powder, and a process for producing acrylic acid by gas phase oxidation of propane using the catalyst.
